Definitions
- the invention relates to a winding device for winding a material web to a winding roll, with a roller carrier that is driven by at least two Has role recordings, each between one Changing position and an exchange position shiftable are a transfer device and a pressure device.
- the invention is in the following based on the Wickeins of Described slides. This is the main application. However, other material webs are in the same way can be wound into winding rolls.
- Transferring the material web from a finished winding roll on a roll core is known per se. There are several ways to do this. With more complex ones Arrangements are made to separate the web of material simultaneously across the entire width, so that a Section is formed that is substantially rectangular runs to the direction of web travel. Simultaneously with that The beginning of the cut formed during cutting is cut Material web around the new winding tube and, if necessary after passing a nip under the further tapered material web directed so that the material web holds itself on the roll core. In this case, a preparation of the roll core is about sticky, not necessary. In many cases such preparation is not desired at all, because you want to save costs. In simpler ones Transfer devices become a cutting knife across to the material web process.
- the invention has for its object a winding device with essentially the same high winding quality operate regardless of the winding direction can.
- This task is the beginning of a winding device mentioned type in that the role recordings can be driven in two different directions of rotation are that a first material path, on the End the web in a first direction the winding roll runs up, and a second web path, at the end of the material web into a second Direction on the winding roll, are provided, and that the transfer device is a first separating device, from the first side into the material web is retractable, and a second separation device, from a second side into the material web is retractable.
- the two Separators are mirror-symmetrical to each other are. Exact symmetry is not required. Smaller deviations, for example may be due to design, are readily permitted. If the two separators essentially are mirror-symmetrical to each other, then separation is carried out by the two separation devices in the same way, and the web becomes independent of which separator is active the same way around the new winding sleeve led around. The quality of the first winding layers is So the same for both winding directions. It is already At the beginning of the winding process, make sure that the Practical in both winding directions be started right away.
- Each separating device preferably has a counter-holder on the opposite side of the web on.
- the counterholders are also mirror-symmetrical to each other built and arranged and on different Adjustable sleeve diameter.
- Such one Counter holder makes it easier to cut through the material web. It forms, so to speak, a bar on which the material web is sheared off by the separating device can be. This also applies if the separating device and the counter-holder is not like scissors, is formed with cutting edges touching each other.
- the counterholder When the counterholder is brought up to the material web then it prevents the material web from becoming too strong evades and later forms folds on the winding tube. In other words, it creates tension in the web of material, which is sufficient to cover the material web with a Being able to cut through the cut and folds to prevent at the beginning of the winding process.
- the counter-holder is a Separating device is arranged on a carriage, compared to a knife unit of the other separating device is relocatable. If you have two separators want to use turns with regard to the counterhold the problem that only a limited one Space is available. If you now the counter-holder which makes a separating device relocatable, then you take it out of the scope of the other separation device move out when this separator in Function should be set. So you create on simple Way the required space for the Separating device without the function of the counter holder for give up both winding directions.
- the counter-holder has a lever arm which is pivotable on the carriage is.
- an auxiliary arm is arranged opposite the lever arm is controlled pivotable and has a separating edge.
- the auxiliary arm thus forms the actual functional element, that used to cut the web of material becomes.
- the separating edge must not necessarily like scissors with the Interact separator. It is enough if it applies tension to the material web, which is sufficient for the separating device to make an impact cut can execute.
- the auxiliary arm in a position can be positioned tangentially to a winding tube to which the material web is to be transferred. In order to is the free path of the material web when cutting, into which the separator is immersed, very briefly.
- Each separating device advantageously acts on the entire width of the material web at the same time. In order to arises when severing an essentially to Running direction right-angled cut. The following wound material web is thus over the entire Width evenly wrapped.
- the pressure device preferably has a pressure slide on, which can be moved relative to the roller carrier is, the receiving the separation devices Sled can be moved relative to the pressure sled are.
- a shiftable pressure slide it is ensured that the diameter of the winding rolls can enlarge without the role recordings have to be moved.
- the pressure slide ensures that the pressure roller always with the necessary pressure on the Winding roller can be applied to the winding hardness one to give predetermined course.
- the separators are, however, relocatable compared to the pressure slide, so that they do not interfere with the winding.
- Each separating device preferably has one in the Material web retractable guide roller on one Carrier is arranged, with a knife opposite Carrier is pivotable.
- each counter holder has a deflection roller is associated with the interposition of the Material web behind the separation point to the new winding tube can be put on and forms a catch nip. If that Knife has cut through the material web, then the beginning of the material web formed by the cut practically immediately after separating into the nip between the winding tube and the guide roller and held there by the subsequent material web. After a few turns, the material web is then through their own tension so on the winding sleeve noted that no additional holding means are more needed. A preparation of the winding sleeve, So sticking is not necessary.
- Fig. 1 shows a winding device 1 with a machine frame 2, in which a roller carrier 3 is arranged.
- the roller carrier 3 is symbolized here by a circle. It has two driven roller seats 4, 5 on, the drives of the roller seats 4, 5 a Winding roll 6 either clockwise (as shown) or can drive counterclockwise. The drives are therefore reversible.
- the roller carrier 3 also has a drive 7, the two Roll holders 4, 5 between a winding position, in which the roll holder 4 is currently arranged, and an exchange position in which the roll holder 5 is arranged, can shift.
- the roller seats 4, 5 are arranged on arms or plates that can be rotated are, so that the roller seats 4, 5 pivoting movements run through the circular line of the roller carrier 3 are shown. But it is also possible that the Role recordings 4, 5 shifted linearly or in another way become.
- a pressure roller 8 is on a pressure slide 9 arranged.
- the pressure slide 9 is using a Drive 10 always positioned during winding so that the Pressure roller 8 with a predetermined pressure against one Winding roll or a winding tube 11 is pressed, the is in the roll holder 4, which is in the winding position is arranged. With increasing diameter the winding roller in the winding position becomes the slide 9 relocated, i.e. moved away from the roll holder 4, so that the pressure roller 8 always a uniform Can exert pressure on the winding roller to the To influence winding hardness favorably.
- the two slides 14a, 14b are essentially mirror-symmetrical to each other, so that mutually corresponding parts with the the same reference numerals are provided for the upper carriage the addition "a" and for the lower Carriage carry the suffix "b".
- Each carriage 14a, 14b initially has a drive 15a, 15b with which he is opposite the pressure slide 9 is movable.
- the carriage 14a, 14b points over it in addition, a second pair of guide rollers 16a, 17a; 16b, 17b on, with the deflection rollers 16a, 17a and 16b, 17b a lever 18a, 18b with a drive 19a, 19b are.
- the drive 19a, 19b can the lever 18a, Swivel 18b.
- the counter holder 20 has a lever arm 21 (explained only for the counter-holder 20a), on which an auxiliary arm 22 is arranged.
- the lever arm 21 is with the aid of a drive 23 opposite the carriage 14a pivotable.
- the auxiliary arm 22 is by means of a Drive 24 pivotable with respect to lever arm 21.
- At the Auxiliary arm 22 has a separating edge 25.
- the Auxiliary arm 22 can, as shown for the counter holder 20b is positioned so that it is essentially is tangential to the winding tube 11, which in the Winding position 4 is arranged.
- the lever arm 21 opposite the slide 14 and the auxiliary arm 22 pivoted relative to the lever arm 21.
- the counter-holder 20 is assigned, pivoted so that the guide roller 17 with the interposition of the material web to be wound up 26 comes into contact with the winding tube 11.
- the knife 31 goes across the entire width of the winding device 1, is thus able to the material web 26 with a essentially perpendicular to the running direction To cut through, so-called a blow cut perform.
- a blow cut perform Through the carrier 32, the material web then passed around the winding tube 11.
- the Separating device 27a, 27b forms together with the counter-holder 20b, 20a on the opposite side of the Material web 26 a transfer device.
- the material web 26 at the moment of cutting through the lower pulleys 16b, 17b and then runs clockwise around the winding tube 11. After that, she will go over the Deflection roller 30 of the upper separating device 27a, while from below the auxiliary arm 22 of the counter holder 20b has been positioned opposite the material web 26.
- the Material web 26 touches. There is only one relative short free path between the winding tube 11 and the guide roller 30.
- the knife 31 from the upper Separating device 27 retracted into the material web 26 the material web 26 is severed, as long as there is enough tension between the winding sleeve 11 and the guide roller 30 maintained can be.
- material webs 26 the more flexible are, for example with certain plastic films, becomes the material web when the knife 31 is immersed pressed against the separating edge 25 of the counter holder 20b. On the one hand, this further shortens the free path length, because now there is only one path length between the winding tube 11 and the separating edge 25 is available.
- the separating edge 25 enables shearing the material web 26.
- the curved carrier 32 now guides the cut one Material web, more precisely, the beginning of which around the winding sleeve 11 around.
- the beginning then gets into the nip between the deflection roller 17b and the winding tube 11, namely, the beginning comes under the requested Material web that runs around the deflection roller 17b.
- the material web 26 is thus caught and by subsequent ones Material web layers held on the winding tube 11.
- FIG. 2a shows a state in which the winding roll 6, which turns clockwise, almost finished wrapped has been.
- the pressure roller 8 on the pressure slide 9 is in permanent contact with the winding roll during winding 6th
- the lower carriage 14b then moves onto the winding tube 11 too, until it stops at a stop 34 comes. Simultaneously with this movement or a little later the counter holder 20b is pivoted as this is shown in Fig. 1.
- the lever 18b is pivoted up so that the deflection roller 17b on the winding tube 11 is present. This achieves the situation in Fig. 1 is shown. The separation process described above can then be done.
- Fig. 2 From Fig. 2 it can be seen that the material web 26 in a first material web path through the winding device 1 has been passed. This first web path involves touching the pulley 12, a partial loop around the guide roller 13 and a loop around the deflection rollers 16b, 17b. The web of material then reaches the pressure roller 8 from below.
- the linear movements can often be done by swiveling movements be replaced.
- the evasive movements of the Bracket 20 opposite the separator 27 the other side of the material web 26 can also be applied to others Way to be realized. However, it is advisable when the counter holder moves away from the winding roll 6 movement of the other separator 27 not to hinder.
